What is the shape of fringes in Young's double slit experiment?
Find the maximum value of y =x-x^2
dy/dx=1-2x=0 x=1/2 y=1/4
The velocity of Image from a spherical is always opposite to velocity of the object if the object is moving along the principal axis of the mirror. True or False?
False; the above answer is true only if the mirror is at rest. However, if mirror moves parallel to the principal axis, Image velocity may be along velocity of the object.
